Problem creating sun-cmp-mappings.xml with xdoclet

Question

I am using xdoclet to create a deployable ear file for the Sun ONE app. server. I am having problems getting a correct sun-mappings.xml file with the correct cmr relation fields.
As an example I created two beans; Account and AccountGroup. AccountGroup has a 1:n relation to Account via the cmr field account. If I look at the resulting sun-mappings file I also get a cmr field "account" in the Account bean, which shouldn't be there.
Can anybody give me a clue what's wrong with this code.

Here is a link to my patch:
http://opensource.atlassian.com/projects/xdoclet/secure/attachment/10294/sunone-rel.patch
Since the patch was created based on a 1.2.0 it is possible that you have to edit in my changes manually.
Note also that my version doesn't support the "target-" attribues. You have to have CMR methods on both sides of the relationship. If one of the methods shouldn't be accessible you can leave out the interface-method tag, and the method will then act as a just a placeholder for xdoclet tags.
For what it's worth we are using my patched xdoclet module to generate descriptors for several hundred CMP/CMR beans and it works perfectly.
